Summary:
I.Daubechies et al. have shown that a new class of unconventional analog-digital (A/D) converters, called β-encoder, exhibits exponential accuracy in bit rates while possessing self-correction property for fluctuations of amplifier factor β and quantizer threshold ν. This paper gives optimal values of β and ν to be designed with their unknown errors for given scale, bit budget and tolerance of quantizer in the β-encoder. Futhermore, a new A/D converter, called negative β-encoder, is introduced so as to improve the variance of quantization error of β-encoder.
